| 摘 要： | 应用SOLA—VOF方法研究了板坯连铸结晶器自由表面的形状及钢水流动行为，计算得出了具有实际物理意义的液位波动值．通过数值模拟浸入水口出流角度及出流速度对液位波动的影响关系，指出液位波动的波形与回流区大小及位置密切相关，并分析了液位波动的形成原因．

| Abstract: | Using the SOLA-VOF methodology, the shape of free surface and the flow pattern of the molten steel in the mold of a continuous slab casting have been simulated and the free surface height is calculated. Based on the obtained relationship between the surface oscillation amplitude and the continuous casting parameters, such as the port inclination degree and the outlet velocity of the submerged entry nozzle, it is pointed that the surface oscillation morphology is inherently influenced by the size and the position of the circumfluence region in the mold. The mechanism of the formation of surface oscillation is also analyzed. |
